Bad rattle in my washing machine and subsequent nondrainage

SOURCE: Whirlpool Duet Sport Washer will not drain - F-21 error

Perfect! Yes, they aer 1/4" 6pt screws. I didn't have to lift my washer, but the previous tech had put in 1 screw crooked, so that was FUN! I had cut out an opening on an old cracked tote and was able to hold all the water as long as I transferred some to a bunch of tupperware. Make sure you line up the upper mark on the white drain plug before putting back in. The tote was getting overloaded and I didn't notice the alignment marks until after having some water overflow. Just a heads-up if anyone has an emergency and HAS to get the plug back in in a hurry.

I found:
Wife's Victoria's Secret panties
2 dimes
4 pennies
some legos
a metal nut
pencil eraser
wall anchor
some legos

You will need to replace the drain pump motor. The pump impeller has separated from the motor shaft. You can push it back on, but it will just come off again. I have not tried adding adhesive because I didn't want a call back. That may work if you want to try it. To replace pump motor:
Take the rectangular recess out by using a putty knife on the left or right side, Remove phillips screws mounting pump. Pull machine forward about two feet to allow you to tilt the machine back to lean it against the wall. Reach under to access the pump. It is held in place by a plastic tab you can depress to remove, but if you break the tab, don't worry, as the mounting screws will hold your pump in place just fine when reinstalled. Remove pump by disconnecting hoses and electrical plug. Change out pump motor (three phillips head screws)

That sounds like a clutch problem - probably just worn and need replacement. Will definitely need to pull to find exact fault.

I had a coin washer and dryer.The slider has little fingers(metal)that slide over the coins.If the coin isn't placed and the slider is pushed hard will jam. Mine had a side cover with a lock. Open that and there is a long rod that has to be unscrewed to remove the lock box,then you should is what went wrong.Hope this helps>

I have had this code three separate times. The first time service man came and cleaned out the filter. This is behind the lower front panel and can be removed by hand. The cartridge style filter is located at the pump in the lower right of the unit. Have something available to catch the draining water as you loosen the filter. The second time I received this code I found a blockage in the drain hose at its bend. The third time no hose blockage, no filter clogging, but the pump impeller was jammed by an elastic strap that had made it through the filter. I removed it through the supply side of the pump seen after filter is removed.
